You define two functions with the same name, say_hello(), in the same interpreter session. However, the second definition overwrites the first one. When you call the function, you get Hello, Pythonista, which confirms that the last function definition prevails.Another technique that some ...

Its previous definition will be overridden by the last one. But, there is a way to achieve similar functionality in Python. We can overload constructors based on the type or number of arguments passed to the __init__() method. This will allow a single constructor method to handle various...

Instance variables are declared at the same level as methods within a class definition.They are usually given private access to restrict visibility.They can receive initial values either when they are declared or in a constructor. Instances variable references may or may not be prefixed with the ...
In a C++ definition of the API, we can replace the references to objects by objects in a class hierarchy, using the pointer-to-implementation idiom within the class. Pointers can be completely managed by factory functions, constructors,copy constructors, anddestructors. ...
